BOTTLE-CLOSURE.

Specification of Letters Patent. P t t 7 1920.

Application filed March 14,1919. Serial No.'282,709.

To all whom it may concern:

Be it known that I, HYMAN GoLDsTmN, a citizen of the United States,residin at Brooklyn, in the county of Kings and tate of New York, haveinvented certain new and useful Improvements in Bottle-Closures, ofwhich the following is a specification.

This invention has relation to closures for ink bottles or the like andhas for an object to provide a novel means for controlling the flow ofmaterial through the closure in the form of a manually operable valve ofa new type adapted specifically for the purpose intended.

Another object of the invention is to providea valved closure of anornamental design, and constructed in such a manner as to permit itsformation of plastic composi tion or other material not acted upon byink or other corrosive fluids.

In addition to the foregoing, this invention comprehends improvements inthe details of construction and arrangement of parts, to be hereinafterdescribed and particularly set forth in the appended claim.

In the accompanying drawings in which similar and corresponding partsare designated by the same characters of reference throughout theseveral views in which they pp Figure 1 is a view in section of a valvedbottle closure constructed in accordance with m invention.

ig. 2 is a sectional view taken on the line 2-2 of the preceding figure,and

Fig. 3 is a view-similar to Fig. 1 with the valve in opened position.

With reference to the drawings 10 indicates a bottle having the neck 11,the latter having a relatively wide bead 12 at its mouth around which ametallic band 13 is embraced. Said band also surrounds the enlarged baseportion 141 of a frusto-conical closure member 15 having its upper endformed cylindrical as at 16. The member 15 is preferably formed ofplastic composition that may be molded into shape and that is notaflected chemically by corrosive liquids. A curved passage 17 is formedthrough the member opening centrally at the bottom thereof and also atthe side. The lower end of the passa e is enlarged to form a circularrecess 18. a vertical passage 19 is also formed in the memberintersecting the passage 17 and opening at it upper end into a recess20.

A composition rod 21 is located in the passage 19 and is formedintegrally at its lower end with a valve member comprising a discousportion 22 to fit the passage 17 and a larger concentric discous port' n23 to fit the recess 18. The periphery o fithe portion 23 is cut away atdiametrica ly opposite points to formnotches or by-passes 24. A notchedwasher 24: may be applied to the disk 23 to form a tight joint with theseat at the bottom of the recess 18. A coiled spring 25 is located inthe recess 20 and embraces the upper end of the rod 21. A cap 26 isprovided, semispherical in form having a central apertured boss 27 toreceive the end of the rod 21 when the cap' is inverted over the top ofthe closure. An annular flange 28 is also formed on the cap to inclosethe upper end of the member 15 to finish off. the appearance of thedevice and to eliminate any corners that .may engage an object toaccidentally open the valve.

An air vent 30 is also formed through the member 15.

In use, the bottle is inverted and the cap 26 pressed inward whereuponthe valve leaves its seat and the contents may flow into the recess 18,through the notches 24 and into the passage 17 as shown in Fig. 3. Whenthe cap is released the valve returns to its seat under the influence ofthe spring and the bottle is effectually sealed, preventing spilling ofits contents and evaporation. Other uses and advantages will readilyoccur to those skilled in the art to which this invention appertains.

While I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts without departing from the spirit ofthe invention or the scope of the appended claim.

Having thus described my invention what I claim as new and desire tosecure by Ilnited States Letters Patent is In combination with a bottle,a closure in the form of a truncated cone having a broad base flange torest on a bottle neck and having its upper end extended to form acylindrical portion, means for securing the closure to the bottle, saidclosure having a circular recess in each end and a curved passageextending from the base recess, and smaller in diameter to form a valveseat, a rod slidable in the closure, a disk formed on the rod to .fitthe base recess and having notches of a depth less than the width of thevalve seat,

a washer having corresponding notches resting on the disk, asemispherical cap member, a peripheral flange and a central bar formedthereon said rod extending into thebar and the flange fitting thecylindrical portion of the closure and a spring in the upper recess andsurrounding the rod to seat the disk, movement of the cap and disk beinglimited to prevent complete withdrawal of the disk from the recess.

In testimony whereof I afiix-my signature in presence of two witnesses.
